I was told that if your S4's ECU has the "M" suffix in its part number
then you have the new upgraded turbos.  You can of course open the
box to look, but VAG-COM also shows that info.  My S4 does show an
M suffix, and has new style badges, but it's a 2001 with a 10/00 build
date, so I think I got the very first batch of the new turbos.  I hope
I'm really that "lucky" :)

So far, no problems with the engine or turbos whatsoever (knock on wood).
